15" Parallel Rulers
Weems & Plath navigation tools are reliable and easy to use. 15" parallel rulers are a necessary tool for every seagoing navigator to measure or lay off courses and distances on a nautical chart. These are built to last - constructed of durable, clear acrylic that is milled with bevelled edges. Each also includes a protractor scale.
These rulers are available here in two versions of handle construction - Brushed Aluminum or Solid Brass. The Brushed Aluminum Arm style is the best seller of these traditional parallel rulers. The Brass Arm style is however assembled with high-quality solid brass arms and handles that adds a bit of traditional elegance to this classic navigation tool.
